"Cover your back" is an expression used to advise someone to be very careful and take all necessary steps to protect themselves from being blamed for something that goes wrong. It means that you should anticipate potential problems and make sure that you have evidence or proof to show that you did everything correctly. For example, if you are working on a project with a team, it is important to document your work and keep copies of any important emails or correspondences so that if something goes wrong, you can show that you did your part and shouldn't be blamed. This expression can be used in both personal and professional situations.
